A ril 28, 1931- E. w. ERICSSON KNIFE Filed Jan. 21, 1930 INVENTOR. 516 M[TltSSan A TTORNE Patented Apr. 28, 1931 Application filed January 21,1930. ,serial No. 422,251.

This invention relates to knives, erasers and the llke; and the ob ectof the'lnvention 1s to-pro-vide a knife of the class specifiedcomprising a handle member consisting of relatively movable 'parts'and ablade member adapted to be arranged between the separate parts of thehandle member and retained in different positions with-respect theretoas well as being readily detachable therefrom 19 whereby new blademembers may be substituted for old or worn out blades; a further objectbeing to provide means for pivotally coupling the separate parts of thehandle member at one end thereof to permit the separation of said partswith means adjacent the other end of said parts for clamping the.

same together and for retaining the blade in connection therewith; afurther object being to so fashion the separate parts of the handlemember at the blade end of the knife as to conform with the contour ofthe shank of the blade in the several positions thereof to key the sameagainst movement independently of the first named securing means; andwith these and other objects in view, the invention consists of theknife of the class and for the purpose specified which is simple inconstruction, eflicient in use, and which is constructed as hereinafterdescribed and claimed.

The invention isfully disclosed in the fol lowing specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which:

Fig. 1 is a side view of a knife made according to my invention showingthe blade in position for use.

Fig. 3 is a section on the line 33 of Fig. 1. i p

Fig. 4 is a side view of the opposite side of the handle of the knifefromthat' shown in Fig. 1, and illustrating the blade in inoperativeposition; and, i

Fig. 5 is a section on the line 55 of Fig. 4. i v In the drawing, I haveshown one construction of knife for carrying my invention into eflect,and inthe several figures, lOi-epresentsthe handle member and 11 theblade. The handle member 10 in the construction shown is fashioned fromtwo sheet metal parts12 and 13, the handle end 14 of which is concaveconvex in cross sectional form so that the marginal edges will abut asindicated at 15, note'Fig.,2 of the drawing, and

the parts 12 and 13 are pivoted together as seen at 16'at the endportion 1 1 whereas the jaw ends 17of the parts 12and 13 are. relativelyflatexcept that the part 12 has arec'ess on its inner surface formed bystamping the material'o'f said partoutwardly in' accord- 5 ance with'thecontour see'nat 18 in Fig. .1 of the draw ng so as to provlde a recess19 of an outline corresponding to that of the shank 'end'20 of the blade"11. In like manner, the

jaw end of the part 13 is pressed outwardly in the manner indicated at21, note Fig. 4.

to form a recess to receive the shank of the blade 11 when saidblade issupport-ed in the positionindicated in Fig. 4 of. the drawing with thecutting end 22 arranged within and between the-parts 12*and 13.

.The outwardlypressed portions 18 and 21 servers key. the blade 11against movement relatively to thehandle'member "10orthe separate partsthereof "when the blade is in the position'sliown in Figs. land 4,andthe aw ends 17 of the parts 12and 13 are clamped together by 'ascr ew23 in threaded engagement with the part 13, and the milled head 24. ofwhich operates to .move the part 12 toward the part 13 to securely'clampthe blade 11 in position, it being understoodthat the blade 11 has'anaperture through which the screw 23 passes asiclearly seen in Fig. 20fthe drawin I Y the use ofthe device, it will be 'understood that theblade 11 isplaced within; and between the jaw end 17 of'the parts 12 and13 in the manner shown in Figs. 1 and 2 of the drawing andthe screwj23'moved into position to securely clamp thefblade'within and between theadjacent faces of said parts, and

the knife is nowin position for use. At this time, it will beunderstoodthat the blade end of the knife "may be of any desiredconftour or size,the handle member or the parts thereof beingv fashioned to correspondwith that of the blade, and when it is desired to discontinue the use ofthe knife, the screw 23 is loosened sufliciently to allow the blade tobe swung into the position shown in Fig. 4: with the blade end 22 withinand between the parts 12 and 13 and the boundaries thereof, after whichthe screwis again tightened to retain said blade against displacement,and in this position the blade may be carried about.

Whenever desired, a new blade or a diff ferent type of blade may becoupled with the handle member by removing the screw and v by swingingthe handle members on their pivot 16. The latter is not absolutely necesjsary as the openingin the blade may extend through one wall thereof toform a notch type aperture as iscustomary inv other types of tools ofthis class. o

It will also be understood that while I have described my invention aspertaining to knives, scrapers andthe like, it will be understood thatany kind or class of blade may be mounted in connection with the handlemember such for example as chisels, saws and ing in jaws in connectionwith which a blade is adapted to be movably supported, a screw passedthrough said jaws and blade for clamping the blade in differentpositions of] adjustment within and between said jaws, one jaw having anoutwardly pressed portion of a contour corresponding to that of theshank of said blade to retain the blade against movement when inprojected position, and the other jaw member having an outwardly pressedportion conforming with the contour of a part of the shank of the bladeto retain the blade against movement with respect to the like, thedistinctive feature of my invention being to providea cheap and yetstrong and durable handle member so constructed as tolpermit themounting of tools of various kinds'and classes in connection thereof,all having a shank of common contour facilitating the mounting of thetool in connection with the handle member. Various changes in andmodifications of the construction herein shown and described may be madewithin the scope of the appended claims without de parting fromethespirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is Q i I V 1. A knifeiof the class describedcomprising two. elongated,fsheetmetal handle mem bers pivotally coupledtogether at one end to permit separation of said handle members in theplane of the'abuttin'g faces thereof, the

other ends of the handle membersterminating in jaws in connection withwhich a blade is adapted to bemovably supported, a screw passed through'said'jaws and blade for and one jaw havingxan outwardly pressed portionprojecting beyond the outer face of the jaw and of a contourcorresponding to that of the shank of said blade to retain thebladeagainstmovement when inprojected ther ends of th handlemembersterminatclamping the blade in different-positions of o adjustmentwithin and between saidjaws,
